The Infiniti mats aren't bad and are a good fit. I do have them, but they are always covered with the WeatherTech All Weather cargo mat which is a plastic mat. Since I always have two large bowling bags or golf clubs back there, I like the way it protects the mat underneath.
LOL - understand completely. You have to pick your battles. But if she wants you get a carpet remnant to put over the WT to keep it from getting scratched....I tend to haul a lot of things in the back and the WT cargo mat protects the floor. When I'm carrying a full load of passengers, it comes out exposing the Infiniti mat. I didn't want to store the Infiniti mat so it has a permanent home under the WT. My wife insists on putting WT mats on top of the original mats. I really don't get it. You don't get any more money for them when you trade the car in. Got to keep the little woman happy.
